This is a very good drink so I am surprised some people didn't like it so much. It's one of my favorite drinks from the US and I'm happy to be able to get it while in a different country. The blueberry compliments the acai well and acai has a unique flavor which I happen to like. Acai is very healthy like organic blueberry but some people may not be used to the flavor of acai from the Amazon rainforest. The drink is sweet enough but not too sweet and just a little tart. It's nice they didn't put too much sugar in it like most drinks. The size is just right for me. This drink is way better chilled.
